Description

Technical Field

[0001] This invention relates to the field of seed drying, specifically to a ventilation drying device for rice sterile line seeds. Background Technology

[0002] Rice male-sterile lines are a special type of rice where the male organs are underdeveloped and unable to produce normal pollen, while the female organs are normally developed. When a rice male-sterile line is crossed with a rice male-sterile restorer line (receiving pollen from the latter), the resulting seeds are the hybrid rice seeds commonly used by farmers in large-scale production. However, these seeds contain high moisture content after harvesting. If not dried promptly, they can lead to mold, spoilage, and pest infestations, reducing grain quality and yield. Drying rice effectively reduces its moisture content, improves quality and storage stability, and extends its shelf life. Furthermore, drying reduces the weight and volume of the rice, facilitating storage, transportation, and processing. Therefore, drying equipment is used to dry rice seeds.

[0003] In existing technologies, during the drying process, hot air dries the seeds from above or to the sides. This requires the airflow to blow downwards to dry the seeds, and the water vapor during the drying process will be blown back towards the seeds with the airflow, affecting the drying of the seeds. If the seeds are dried from below, multiple sets of through holes need to be opened on the bottom plate. However, the seeds can easily clog the through holes, preventing the airflow from passing through smoothly and affecting the drying effect. Moreover, if the seeds are dried from below, the airflow will pass through the seeds above. Since the seeds are piled together during the drying process and have a certain thickness, the seeds on the upper and lower layers will dry unevenly during the drying process, resulting in uneven drying of the seeds. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a ventilation drying device for rice sterile line seeds, so as to solve the technical problems of inconvenience in drying seeds from below and uneven drying.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ventilated drying device for rice sterile line seeds, comprising a dryer, wherein a drying structure is installed inside the dryer, and the dryer is provided with an upper drying chamber, an air inlet chamber, and a lower drying chamber. The drying structure includes two sets of fans and two sets of partition plates, one set of fans being located inside the air inlet chamber and the other set being located inside the lower drying chamber. Each set of partition plates has multiple sets of air holes. The two sets of partition plates are located above and below the air inlet chamber, respectively, forming the boundaries of each chamber. The air inlet chamber is located below the fans. There is a sealing plate that isolates the fan located in the air intake chamber from the lower partition plate. The air intake chamber has first air inlets on both sides and exhaust windows on both sides of the upper drying chamber. The airflow enters from the first air inlet, passes through the upper partition plate, and is discharged through the upper drying chamber to dry the seeds once. Ventilation pipes are also provided on both sides of the air intake chamber, which connect the air intake chamber and the lower drying chamber. The remaining hot air in the air intake chamber enters the lower drying chamber through the ventilation pipes, passes through the lower partition plate from below, and dries the seeds a second time. A cleaning mechanism is installed under each set of partition plates.

[0006] By adopting the above technical solution, seeds can be dried at different temperatures in a convenient manner.

[0015] The invention is further configured such that an air pump is installed on the outer wall of the dryer, the input end of the air pump extends into the interior of the dryer and is connected to an air intake groove, the air intake groove is located above the second turntable, the output end of the air pump extends into the middle of the second turntable and is connected to an air guide pipe, the top end of the air guide pipe is connected to an air jet plate, the air jet plate is located between the upper and lower isolation plates, the airflow enters the interior of the air pump through the air intake groove, is transported to the air guide pipe by the air pump, and is discharged through the air jet plate.

[0016] By adopting the above technical solution, when the seeds move between the isolation plates, the airflow cleans the impurities in the seeds, and the air jet plate can turn the seeds over, thereby improving the drying effect of the seeds.

[0017] The present invention is further configured such that a connecting pipe is installed inside the lower drying chamber, a partition is provided on the outside of the connecting pipe, the partition divides the lower drying chamber into two parts, the connecting pipe connects the two parts of the lower drying chamber, and a second air inlet is provided on the side of the lower drying chamber, the second air inlet connects the lower drying chamber to the outside.

[0022] By adopting the above technical solution, the connecting rod can be moved by the cam, thereby moving the cleaning plate to clean the area below the isolation plate. At the same time, the push plate is moved by the spring rod, which drives the plug to be inserted into the air hole inside the isolation plate to clean the blocked air hole.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] The embodiments of the present invention will now be described.

[0043] Example 1

[0044] Rice male-sterile line seeds are dried using ventilated drying equipment, such as Figures 1 to 11 As shown, the device includes a dryer 1, which has a drying structure installed inside. The dryer 1 has an upper drying chamber 101, an air inlet chamber 102, and a lower drying chamber 103. A collection chamber 104 is provided at the top of the dryer 1, and a feed pipe 2 is connected to the top of the collection chamber 104. Seeds from the outside enter the dryer 1 through the feed pipe 2. A discharge port 107 is provided at the bottom of the dryer 1, through which the seeds are discharged from the dryer 1.

[0045] Inside the air intake chamber 102, below the fan 3, a sealing plate 110 is provided. The sealing plate 110 isolates the fan 3 inside the air intake chamber 102 from the lower partition plate 7. First air inlets 106 are provided on both sides of the air intake chamber 102, and exhaust windows 105 are provided on both sides of the upper drying chamber 101. Airflow enters through the first air inlets 106, passes through the upper partition plate 7, and exits through the upper drying chamber 101, performing primary drying of the seeds. Ventilation pipes 109 are also provided on both sides of the air intake chamber 102, connecting the air intake chamber 102 to the lower drying chamber 103. Remaining hot air from the air intake chamber 102 enters the lower drying chamber 103 through the ventilation pipes 109, passes under the lower partition plate 7, and performs secondary drying of the seeds. The drying mechanism includes two sets of fans 3 and two sets of partition plates 7. The output end of the fan 3 is connected to a fan blade 301 and a fixed plate 302 to drive airflow. One set of fans 3 is located... Inside the air intake chamber 102, another set is located inside the lower drying chamber 103. Each set of partition plates 7 has multiple sets of air holes. The two sets of partition plates 7 are located above and below the air intake chamber 102, respectively, forming the boundaries of each chamber. The two sets of partition plates 7 are arranged at an angle, with the smaller angle of the partition plates 7 located on the side away from the fan 3. The top of the upper partition plate 7 is located directly below the collection chamber 104, and the bottom of the lower partition plate 7 is located directly above the discharge port 107. During drying, the fan 3 located inside the air intake chamber 102 is started. The fan 3 drives the fan blades 301 to rotate. The fan blades 301 draw in the outside air from the first air inlet 106 into the air intake chamber 102, and heat the incoming air through the heating pipe. The heated air passes through the air holes on the partition plate 7 and heats and dries the sliding seeds. The heated air carries water vapor and is discharged through the exhaust window 105, improving the drying effect.

[0046] The dryer 1 is equipped with a first conveyor belt 6, and a pusher pipe 601 is installed inside the first conveyor belt 6. The first conveyor belt 6 is also equipped with a first turntable 602, a second turntable 603, and a third turntable 604. The first turntable 602 is located below the top of the upper partition plate 7, the second turntable 603 is located in a position opposite to the two sets of partition plates 7, and the third turntable 604 is located above the bottom of the lower partition plate 7. The first turntable 602 is equipped with a drive motor 4 on the outside of the dryer 1. The first conveyor belt 6 is distributed on the top of the upper and lower partition plates 7 by the first turntable 602, the second turntable 603, and the third turntable 604, thereby driving the pusher pipe 601 to move on the top of the upper and lower partition plates 7. The pusher pipe 601 can push the seeds to move on the partition plates 7, reduce seed accumulation, and improve the seed movement effect.

[0047] Each set of isolation plates 7 is equipped with a cleaning mechanism below it. The cleaning mechanism includes a connecting rod 10 and a cleaning plate 11. A transmission rod 9 is installed on the inner side of the first turntable 602. The transmission rod 9 is connected to the cleaning mechanism below the upper isolation plate 7. A transmission disc 6031 is installed on the outer side of the second turntable 603. A second conveyor belt 6032 is sleeved on the outer side of the transmission disc 6031. The second conveyor belt 6032 extends to the interior of the lower drying chamber 103 and is also connected to the transmission rod 9. This set of transmission rods 9 is connected to the cleaning mechanism below the lower isolation plate 7. Multiple sets of cams 901 corresponding to the connecting rod 10 are installed on the inner side of the transmission rod 9. The transmission rod 9 is connected to the connecting rod 10 through the cams 901. The top of the cleaning plate 11 is connected to an ejection mechanism for cleaning the air holes of the isolation plate 7, thereby preventing the isolation plate 7 from becoming blocked.

[0048] A support plate 701 is connected to the bottom end of the isolation plate 7. The connecting rod 10 slides horizontally inside the support plate 701. A top plate 1001 is connected to the alignment position of the connecting rod 10 and the cam 901. The top plate 1001 contacts the cam 901. A return spring 1002 and a limiting plate 1003 are connected to the bottom end of the connecting rod 10. The limiting plate 1003 is installed at the bottom end of the isolation plate 7. The cleaning plate 11 is distributed between the two sets of connecting rods 10. A locking groove 1101 is connected to the back side of the cleaning plate 11. A spring rod 1103 is installed inside the locking groove 1101. A push plate 1104 is installed at the top end of the spring rod 1103. Multiple plugs 1105 are connected to the top end of the push plate 1104. Each plug 1105 matches the size of the air hole inside the isolation plate 7. The plug 1105 is conical. The side of the top end of the cleaning plate 11 away from the locking groove 1101 is connected to... The rubber scraper 1102, during the cleaning process, pushes the top plate 1001 via the cam 901. The top plate 1001 then moves the connecting rod 10 as a whole. The movement of the connecting rod 10 causes multiple sets of cleaning plates 11 to move below the isolation plate 7. This allows the isolation plate 7 to first be squeezed and pushed out by the rubber scraper 1102, which pushes the push plate 1104 to align with the air hole. At this time, under the push of the spring rod 1103, the plug 1105 is inserted into the air hole to push out the still stuck seeds, thereby reducing the blockage of the air hole. When returning to the original position, the reset spring 1002 pushes the connecting rod 10 to reset as a whole. At this time, the top of the plug 1105 is a cone, which can convert part of the push force of the reset spring 1002 into the push force of the spring rod 1103, so that the push plate 1104 can be re-inserted into the locking groove 1101 during the reset.

[0049] Please see Figure 1 , Figure 2 as well as Figure 4An air pump 5 is installed on the outer wall of the dryer 1. The input end of the air pump 5 extends into the interior of the dryer 1 and is connected to an air intake groove 501. The air intake groove 501 is located above the second turntable 603. The output end of the air pump 5 extends into the middle of the second turntable 603 and is connected to an air guide pipe 502. The top end of the air guide pipe 502 is connected to an air jet plate 503. The air jet plate 503 is located between the upper isolation plate 7 and the lower isolation plate 7. The airflow enters the air pump 5 through the air intake groove 501 and is transported to the air guide pipe 502 by the air pump 5. It is then discharged through the air jet plate 503. When the seeds fall from the upper isolation plate 7 onto the air jet plate 503, the airflow can clean the impurities in the seeds and turn the seeds over, thus improving the drying effect of the seeds.

[0050] Please see Figure 2 A connecting pipe 8 is installed inside the lower drying chamber 103. A partition is provided on the outside of the connecting pipe 8, which divides the lower drying chamber 103 into two parts. The connecting pipe 8 connects the two parts of the lower drying chamber 103. A second air inlet 108 is provided on the side of the lower drying chamber 103, which connects the lower drying chamber 103 to the outside.

[0051] Example 2

[0052] Please see Figures 12 to 13 This is the second embodiment of the present invention. The difference from the first embodiment lies in the cleaning mechanism. Specifically, the bottom end of the isolation plate 7 is connected to a bracket 702, and the connecting rod 10 slides vertically inside the bracket 702. A top plate 1001 is connected to the position where the connecting rod 10 is aligned with the cam 901. The top plate 1001 is a roller. The cleaning plate 11 is installed above multiple sets of connecting rods 10. Multiple sets of ejector pins 12 are connected to the top of the cleaning plate 11, and the ejector pins 12 are aligned with the air holes inside the isolation plate 7. The diameter of the top of the ejector pin 12 matches the size of the air hole. When cleaning the isolation plate 7, the cam 901 pushes the connecting rod 10 upward, thereby driving multiple sets of cleaning plates 11 to move upward synchronously. This causes the ejector pins 12 to be inserted into the air holes of the isolation plate 7, pushing the seeds blocked in the air holes and separating the seeds from the isolation plate 7. At the same time, the ejector pins 12 are inserted above the isolation plate 7 to disturb the flowing seeds, further improving the mixing effect of the seeds and improving the uniformity of seed drying.

[0053] In the seed drying process of this invention, the seeds are first injected into the collection chamber 104 through the feed pipe 2, so that the seeds fall onto the upper isolation plate 7. Then, the drive motor 4 is started, which drives the third turntable 604 to rotate, thereby driving the first conveyor belt 6 to rotate. The first conveyor belt 6 drives multiple sets of push pipes 601 to move above the upper isolation plate 7. Under the influence of gravity and the push pipes 601, the seeds slide down the isolation plate 7. At this time, the fan 3 located in the air intake chamber 102 is started. The fan 3 drives the fan blades 301 to rotate. The fan blades 301 draw in the outside air from the first air intake port 106 into the air intake chamber 102, and heat the incoming air through the heating pipe. The heated air passes through the air holes opened on the isolation plate 7 to heat and dry the sliding seeds. The heated air carries water vapor and is discharged through the exhaust window 105, improving the drying effect.

[0054] Some seeds that slide down may get stuck in the air holes on the isolation plate 7 due to angle or other issues. At this time, the first turntable 602 will synchronously drive a set of transmission rods 9 to rotate. The transmission rods 9 drive the cam 901 to rotate, and the rotation of the cam 901 will push the top plate 1001 to move. The top plate 1001 will drive the connecting rod 10 and the cleaning plate 11 to move below the isolation plate 7. The top of the cleaning plate 11 will first come into contact with the air holes of the upper isolation plate 7. The rubber scraper 1102 will first push the seeds stuck in the air holes upward to separate the seeds from the air holes. If the bottom of the seeds is still stuck in the air holes at this time, the subsequent movement will... The push plate 1104 is aligned with the air hole. Under the action of the spring rod 1103, the push plate 1104 is pushed upward to insert the plug 1105 into the air hole, thereby pushing out the seed. This reduces the time the seed is stuck in the air hole and improves the efficiency of airflow through the isolation plate 7. Then the cam 901 separates from the connecting rod 10, the cleaning plate 11 returns to its original position under the action of the spring rod 1103, and the plug 1105 separates from the air hole under the action of the inclined surface, pushing the push plate 1104 back to its original position so that it can move back and forth to clean the air hole without blocking it, and the airflow can pass through normally.

[0055] The first dried seeds then fall onto the spray plate 503 through the upper isolation plate 7. At this time, the air pump 5 is activated, and the air pump injects air into the air guide pipe 502. The air guide pipe 502 is connected to the spray plate 503, and the airflow is sprayed out through the spray plate 503, thereby cleaning the seeds and blowing the impurities upward, so that the impurities enter the air intake groove 501. The air intake port of the air pump 5 is connected to the air intake groove 501, so that the impurities can be sucked into the air intake groove 501. Multiple sets of filter elements can be installed in the air intake groove 501 to filter the impurities, improve efficiency, and facilitate seed cleaning.

[0056] Meanwhile, the seeds falling on the jet plate 503 will rotate under the action of gravity and then fall onto the lower isolation plate 7, so that the seeds can be mixed and stirred between the upper and lower layers, thereby drying the seeds evenly.

[0057] When the seeds fall onto the lower isolation plate 7, they move towards the discharge port 107 under the influence of gravity and the pusher pipe 601. At this time, part of the hot airflow in the air inlet 102 passes through the ventilation pipe 109 and enters the lower drying chamber 103. The temperature of the airflow is controlled (if the airflow temperature is too high, the second air inlet 108 is opened; if the airflow temperature is too low, the heating pipe in the lower drying chamber 103 is activated). The fan 3 in the lower drying chamber 103 is also activated, allowing the airflow to pass through the lower isolation plate 7 to further dry the seeds. Part of the airflow passes through the connecting pipe 8 to dry the seeds on another part of the lower isolation plate 7, improving the drying effect. A connecting rod 10 and a cleaning plate 11 are also provided below the lower isolation plate 7. A set of transmission rods 9 are driven to rotate by the second conveyor belt 6032 on the side of the second turntable 603, thereby moving the connecting rod 10 and the cleaning plate 11 below the lower isolation plate 7 back and forth to clean the air holes of the lower isolation plate 7, improving the cleaning effect.

[0058] The dried seeds will be discharged from the dryer 1 through the feed port 107.
